Annie221, looking at things quite bluntly, you are older now, you looked after one previously but are now being asked to take more than one both at the same time. Plus no doubt the original child during sickness, school holidays etc. Plus any more that may come along - because you will have set a precedent. Let's face it you now would like some time to enjoy your retirement while you both have your health, mobility, inclination and each other! Wanting to enjoy your lives is not selfish, you are being honest in admitting it. However, i can predict this being a future bone of contention if you don't set some ground rules now and inform both sets of parents. Tell them kindly but very firmly what you are and are not prepared to do so that any future claims of favouritism can be knocked into touch, but don't forget that you are not obliged to provide childcare. Maybe offer the new candidates 2 days a week, after all there was only one previously. Don't be emotionally blackmailed & listen to your gut instinct. A dear friend of mine decided on a certain age and then told her children no more childcare beyond that point and gave them due warning and she stuck to it (and in hindsight is glad she did, although it was hard at first because she's one of life's helpers).
